EXT3, EXT4, Btrfs Ubuntu Netbook Benchmarks

"Last month we published benchmarks of EXT4 comparing this
file-system's performance when it was first marked stable in the
mainline kernel and then where it is at now in the Linux kernel
while testing every major release in between. This article was
followed up by a Btrfs versus EXT4 comparison using the Linux
2.6.33 kernel to see how the two most talked about Linux
file-systems are battling it out with the latest kernel. After
those Linux file-system benchmarks were published, we received a
request from Canonical to look at the EXT3 performance too. With
that said, we have done just that and have published EXT3, EXT4,
and Btrfs benchmarks from Ubuntu 9.10 and a Ubuntu 10.04
development snapshot from an Intel Atom netbook.

"For this round of testing we used a Samsung NC10 netbook that
was loaded with an Intel Atom N270 CPU clocked at 1.60GHz, an Intel
945GME + ICH7-M motherboard with integrated graphics, 2GB of
DDR2-533MHz system memory, and an 32GB OCZ Core Series SSD. We
tested clean installations of Ubuntu 9.10 "Karmic Koala" and a
daily snapshot (2010-02-16) of Ubuntu 10.04 "Lucid Lynx" on this
netbook using the three file-systems: EXT3, EXT4, and Btrfs. Ubuntu
9.10 uses the Linux 2.6.31 kernel while Ubuntu 10.04 is using Linux
2.6.32.

"Ubuntu Karmic and Lucid were tested with EXT3, EXT4, and Btrfs
using the SQLite, Compile Bench, IOzone, Dbench, FS-Mark, Threaded
I/O Tester, PostMark, and Unpack-Linux tests available through the
Phoronix Test Suite. Each file-system was mounted with its default
mount options and both releases of Ubuntu were left in their stock
configurations."
